Anyone know where I might can buy a Turbo Boost Control Solenoid for a 1988 Turbo Coupe? Local Ford dealer says Ford lists it as an obsolete part. None of my local parts stores has it, nor can get one. The Ford part number on the side of it is E8SE-9K378-AA. I broke mine taking off an old vacuum hose!

I haven't heard of a new one in many years. Unless you want one to keep it original, there a many aftermarket brands that do a better job and get around the inherent limitations of the stock valve. I'm partial to the Gillis valves but there are others out there.

Thanks for the quick reply, Pete.

Can you provide some sources/ links to websites where I can purchase aftermarket units? I'm not real knowledgeable about them.

For what it's worth, way back (~14 years or so) when I broke the nipple off my factory BCS, I just JB Welded it back on and it's still tightly attached today. Of course, nowadays it just sits on a shelf anyways...

Thanks for the link, Brian. I Gorilla Glue'd it back together after couldn't find one locally, since I've got to drive it to work tomorrow. But, I need to buy one since I'm not sure how long my redneck engineering will hold up. I didn't realize there were better aftermarket units that the stock Ford ones. This is my first Turbo Coupe, and has been a learning experience getting it back running. I bought it at an auction sitting in a field, and trailered it home.

Another question... I checked out the Boostvalve.com link. BUT, my factory boost control solenoid has a 2-pin connector on the side of it. I notice that the one sold by BoostValve doesn't appear to have any wire connectors. Will this cause any problems? What does the 2-pin connector on the stock solenoid go to? Thanks!

You leave it hanging. The one I linked is a manual boost controller. You use the knob to dial in the boost you want.

Gerald,

Here a really good picture of how everything works, both basic and in the "way out there world". I'm still researching costs of the basic unit, but in the mean time, this is a good read.

http://blog.perrinperformance.com/boost-...explained/

There are several manufacturers of EBC systems and several "could" be adapted. I agree with "B" regarding the use of a manual valve. We have all used the "Gillis" valve for years.

The costs for EBC valves start in the $120 to $130, where the Gillis in today's pricing is still (I believe) under $50.

Hope this helped.

Here's another less expensive alternative. I have two of his boost valves, one on each car, and they work great.
